Abstract
Aspects are disclosed for sequencing and correlating a positioning reference signal. A set of reference symbols associated with a reference signal are allocated, and a base sequence is generated. An extended sequence, which includes the set of reference symbols, is then provided according to the base sequence. The extended sequence is then transmitted in a sub-frame designated as an idle period. A sequence of reference symbols is received from a base station during an idle period of the base station. A replicated sequence of reference symbols is generated, and a correlation is ascertained between a subset of the received sequence of reference symbols and a corresponding subset of the replicated sequence of reference symbols. The received sequence of reference symbols is then identified according to the correlation.
